Nighttime anxiety is one of the most common forms of stress—and one of the most frustrating. You finally lie down to sleep, but as soon as it’s quiet, your mind starts racing. Every worry, to-do list item, and past conversation suddenly becomes urgent.

If this sounds familiar, you’re not alone. Nighttime anxiety is extremely common, and the good news is that there are science-backed ways to calm your mind and sleep more peacefully.

Anxiety is an umbrella term that covers many different conditions — each with its own symptoms, triggers, and treatment options. Knowing the differences can help you understand what you’re experiencing and which support strategies may help.

Anxiety is one of the most common mental-health experiences worldwide — yet most people still misunderstand what it truly feels like. It’s not just “worry” or “stress.” Anxiety can affect every part of your mind and body, often in ways that are invisible to others.
